- macvdmtool is a tool developed by marcan under the AsahiLinux project that simplifies putting Apple Silicon or Intel Macs with T2 chip (2018 and later) into DFU mode using a terminal command.
- Prerequisites include two Macs: a functional host Mac (Apple Silicon-based) and a target Mac that powers on and boots to question mark or recovery mode.
- Setup involves installing Xcode command-line tools, Apple Configurator 2, cloning and compiling macvdmtool, copying it to path, and connecting the Macs via a compatible USB-C or TB3/TB4 cable.
- To enter DFU mode, run 'sudo macvdmtool dfu' on the host Mac, then restore using cfgutil, Apple Configurator 2, or Finder, with IPSW files available from sources like Mr. Macintosh's database.
- Future automation may include scripts for downloading latest IPSWs and integrating with tools like Munki, with further resources and support available via GitHub and MacAdmins Slack.
